Is the db killer removable?
Altering the db killer and the associated welds/safety screws violates product compliance and makes it illegal for road use.
Is there a removable GPR catalyst?
No, in some countries this will make the bike illegal for road use. It may also require further ECU adjustments to protect the engine and ensure optimal performance. It is the owner's responsibility.
95Db limit for Tyrol / Switzerland.
No, but this limit only applies to local residents, not tourists.
High mounting position. Installing the racing collector may trigger a check engine warning due to changes in exhaust parameters, resolvable only by installing an additional control unit.
It is mounted in a side position.
Silencer shape: Round.
Racing product, not road legal, no structural modifications to the bike are required for installation. It is recommended to read the instructions in the package or watch tutorials available on YouTube.
The exhaust features a removable db killer (noise limiter) for racing use; removing the db killer is not ONLY illegal, but the customer assumes the responsibility for using the bike strictly on the track, without saddlebags, flashlights, license plate holders, or other parts that would conflict with the different gas angle following the conversion to race version. Abuse of this situation on the road will lead to loss of product warranty, and any claims will be rejected. From the date of purchase, with the right to repair with return to the GPR factory or the nearest official distributor at the customer's expense.
GPR cannot provide a new silencer instead of the one to be repaired; the customer must agree to reassemble the original exhaust or wait the standard time for repairs.
